Here is a little project i have for my 5 year old daughter, its 80 cm tall total, 60 cm to cooking top, and 40 x 40 cm,
and there is plexi in the door to be able to look inside.
Planing to put a little led light inside with a switch to turn it on when you turn on the oven.
Made out of 6 mm mdf, and spray painted.
